Abstract
A centrifugal separator comprises a driving unit, a power transmission unit including a driving shaft and a crown mounted to one end of the driving shaft, a rotor having a rotor body to which an insertion hole into which the crown is inserted is formed and including a sample holding member, the rotor being formed with a projection member so as to extend outward, a rotor casing into which the rotor is accommodated in a rotatable manner, and a receiving member disposed on the rotor casing side to receive the projection member. In a state that the crown is inserted into the insertion hole from a bottom wall side of the rotor casing, a first distance between the bottom wall of the rotor casing and a front end portion of the crown is made smaller than a second distance between a bottom portion of the projection member and a bottom portion of the insertion hole formed to the rotor body. The receiving member is formed as an annular recess having a depth larger than a difference between the second distance and the first distance.
